[antlr-interest] CppCodeGen patch

[Brad Schick]

I'm not sure if people normally submit patches here, but I have a
simple one :) Under VC7.1 antlr's generatd C++ code causes *many*
warnings because the type returned by std::string::lengh() is larger
than type int.

This patch changes CppCodeGen to use the typedef from the 
basic_string class. I believe this should work on other compilers 
with compliant stl. Patch was created against 2.7.4rc1
